Plugin SDK reference

Manifest host surface fields

Manifest fields that contribute a concrete host surface: an icon, a command, a server, a panel, a widget, a runner, a channel, or a backup resource. Part of the Plugin manifest reference; the top-level field reference lists every field.

Plugin icon

Place the portable plugin icon at assets/icon.png, relative to the plugin root. No manifest field is required. Use a square PNG that remains recognizable at 16 px; 512×512 is recommended. Missing, unreadable, or invalid icons are ignored and do not invalidate the plugin.

OpenClaw adopts this fixed package path as its icon convention, matching the path proposed in Agent Plugins 1.1. Other Agent Plugins consumers may not discover it unless that proposal is adopted. The fixed path keeps packages portable and inspectable, avoids manifest path indirection and precedence rules, and lets OpenClaw render the icon without a runtime network request. Top-level plugin-branding icon URLs are not loaded; provider-auth artwork remains server-owned catalog metadata.

Prefer top-level sessionRouteStateOwners for static doctor ownership. The older doctorContract.sessionRouteStateOwners: true declaration plus a sessionRouteStateOwners export from doctor-contract-api remains supported for external plugins, but is deprecated. When the manifest field is present, OpenClaw uses it without loading the doctor-contract module. Removal plan: remove the module fallback in OpenClaw 2027.1 after the external-plugin migration window.

Set doctorContract.configRepair: true when the doctor-contract module exports non-empty legacyConfigRules, a normalizeCompatibilityConfig function, or both. One declaration covers the complete config-repair artifact.

Bundled plugins declare each state migration in execution order so Doctor can plan its owner and receipt without loading plugin code:

json
{  "doctorContract": {    "stateMigrations": [      { "id": "legacy-cache-to-state" },      { "id": "session-owner-repair", "doctorOnly": true, "phase": "after-session-repair" }    ]  }}

The array must match the migration IDs, order, doctorOnly flags, and phases exported by the doctor-contract module. The older value true still declares the dynamic module. Installed external plugin manifests remain outside the copied-state and candidate content identity, including when they use the descriptor array. Candidate validation must bind those artifacts separately. Until then, Doctor records an explicit planning refusal instead of treating an installed manifest as write authority.

The Codex plugin sets doctorHealthChecks: true when its public API exports health-check registration. Doctor checks the selected plugin's trust before loading this surface. Older installed versions without the declaration skip Codex health registration without preventing other checks; a declared but missing or broken API remains an error. This does not grant plugin capabilities or replace upgrade consent.

Channel plugins maintained in the OpenClaw source tree also expose these config exports through a pure config-doctor-api.ts entrypoint. The core package retains that entrypoint alongside its channel schemas when the plugin runtime is distributed separately. This lets doctor --fix migrate older configuration before plugin installation or capability consent. An installed plugin's doctor contract remains authoritative; retained entrypoints do not expose state migrations, install plugins, or grant capabilities.

Transcript sources reference

transcriptSources maps provider IDs to static setup descriptors. Each key must also appear in this plugin's contracts.transcriptSourceProviders; descriptors for undeclared IDs are ignored. Names and setup controls are available from the prepared manifest snapshot without importing provider runtime.

json
{  "contracts": { "transcriptSourceProviders": ["captions"] },  "transcriptSources": {    "captions": {      "name": "Captions",      "autoStart": { "accountId": "optional", "meetingUrl": "required" }    }  }}

name is an optional display name. autoStart advertises setup controls to Gateway clients through transcripts.status. Its only keys are accountId, guildId, channelId, and meetingUrl; each value must be "required" or "optional". An explicit empty object supports setup without locator controls. Omit autoStart for sources that only attach to an already-active meeting bot. Malformed objects, unknown locator keys, or invalid modes do not advertise partial setup. Title and custom session ID remain existing configuration fields, not locator descriptor keys.

Setup requires an enabled plugin. Runtime capabilities remain observed facts: an absent canStart does not hide the manifest descriptor, while an observed canStart: false prevents new setup. The descriptor does not change acceptance of existing transcripts.autoStart config or provider start semantics. Existing source edits preserve configured fields when metadata is unavailable.

backupResources reference

Use backupResources to declare plugin-owned durable data that backups must include, or generated data that OpenClaw can safely omit and regenerate after restore. The backup planner reads this metadata without loading plugin runtime or modifying plugin files. Only effectively activated, loadable plugins contribute resources; disabled or unloadable plugins cannot exclude data.

json
{  "backupResources": [    {      "disposition": "include",      "scope": "state",      "relativePath": "example-plugin/durable-state"    },    {      "disposition": "regenerable",      "scope": "agent",      "relativePath": "example-plugin/generated-cache"    }  ]}

Each entry is a closed object with exactly these fields:

Field Required Type What it means
disposition Yes "include" | "regenerable" Protect durable data from exclusion, or identify data that can be omitted and rebuilt.
scope Yes "state" | "agent" Resolve the resource under the state directory or each configured agent directory.
relativePath Yes string Strict relative POSIX path contained by the selected scope's authoritative root.

Plugin identity and its trusted root come from manifest discovery; resource entries cannot declare or override an owner. relativePath must not be empty or absolute and must not contain backslashes, NULs, empty path segments, ., .., Windows drive or UNC prefixes, URI-like values, or any path that escapes its selected anchor. Invalid entries are rejected rather than normalized.

The planner deduplicates resources deterministically. A narrower regenerable declaration wins over a broad configured state or agent root. Among plugin resource declarations, only an explicit nested include protects a descendant and keeps its excluded ancestors traversable. Explicit config, credentials, workspace, and nested agent paths also remain protected. Omit only data the plugin can recreate. openclaw backup create --only-config does not inspect plugin backup metadata.

MCP server reference

mcpServers lets a native plugin ship an MCP server, including an MCP App, without requiring operators to duplicate its static process definition in openclaw.json:

json
{  "mcpServers": {    "example": {      "transport": "stdio",      "command": "node",      "args": ["./mcp-server.js"]    }  }}

OpenClaw includes these servers only while the owning plugin is enabled. Relative command, args, cwd, and workingDirectory paths resolve from the plugin root. User configuration remains authoritative: mcp.servers.<name> can replace a plugin default or set enabled: false to omit it. MCP App rendering and server-tool calls still require the normal MCP Apps setting and effective tool policy; declaring a server does not bypass either boundary.

controlUi reference

controlUi declares a trusted native browser entry and optional stylesheets for the Control UI. Paths are relative to the plugin root and must name compiled JavaScript and CSS. Assets follow the Gateway's authentication policy, are captured as immutable revisions, and refresh only through the explicit UI reload flow.

User-installed native UI requires Settings → Labs → Custom plugin UI (gateway.controlUi.experimental.customPlugins, default false). Native UI from enabled bundled plugins remains available. See Enable custom plugin UI for restart and browser reload requirements. This gate does not disable the plugin's backend APIs or the sandboxed dashboard bindings below.

json
{  "controlUi": {    "entry": "dist/control-ui/<content-hash>/index.js",    "styles": ["dist/control-ui/<content-hash>/index.css"]  }}

Use package.json.openclaw.controlUi for the source entry and let openclaw plugins build generate this declaration. Native UI executes with the browser application's trust; it is distinct from the scoped dashboard widget bindings below. See Feature plugins for authoring, replacements, reload, and activation receipts.

dashboard reference

dashboard lets an enabled plugin expose existing Gateway RPCs to granted dashboard widgets without adding plugin policy to core. Data bindings must name a method the same plugin registers with operator.read; action verbs must name a method it registers with operator.write. A mismatch rejects the plugin during registration.

json
{  "dashboard": {    "dataBindings": [      {        "id": "items.list",        "method": "example.items.list",        "description": "List example items."      }    ],    "actionVerbs": [      {        "id": "refresh",        "method": "example.items.refresh",        "description": "Refresh example items.",        "paramShape": {          "type": "object",          "additionalProperties": false,          "properties": {            "force": { "type": "boolean" }          }        }      }    ]  }}

The manifest ids are plugin-local. Widget grants use <plugin-id>.<id>, such as example.items.list and example.refresh. To keep the persisted grant namespace unambiguous, OpenClaw escapes % and . in the plugin-id segment as %25 and %2E; ordinary plugin ids keep the natural form. paramShape is an optional JSON Schema applied to the action params object before OpenClaw invokes the plugin RPC.

catalog reference

catalog provides optional display hints to plugin browsers. Hosts may ignore these hints. They never install or enable the plugin, and they do not change its runtime behavior or trust level.

json
{  "catalog": {    "featured": true,    "order": 10  }}
Field Type What it means
featured boolean Whether catalog surfaces should feature this plugin.
order number Ascending display hint among curated plugins; lower values appear earlier.

cliCommands reference

Declare every plugin-owned root command in cliCommands so root help and command-owner routing stay metadata-only:

json
{  "cliCommands": [    {      "name": "example",      "description": "Manage the example integration",      "hasSubcommands": true    }  ]}

The manifest row is the canonical help text. Register the same command at runtime with api.registerCli(..., { descriptors: [...] }); runtime descriptors may additionally provide machineOutput. Nested commands such as openclaw nodes <feature> are not root commands and do not belong in cliCommands.

commandAliases reference

Use commandAliases when a plugin owns a runtime command name that users may mistakenly put in plugins.allow or try to run as a root CLI command. OpenClaw uses this metadata for diagnostics without importing plugin runtime code.

If a plugin fails to load, invoking its declared runtime-slash command in chat returns the plugin name, a short failure reason, and recovery guidance (openclaw doctor and gateway logs). Unknown commands and commands belonging to intentionally disabled plugins keep their normal handling; manifest ownership alone does not make a command executable.

json
{  "commandAliases": [    {      "name": "dreaming",      "kind": "runtime-slash",      "cliCommand": "memory"    }  ]}
Field Required Type What it means
name Yes string Command name that belongs to this plugin.
kind No "runtime-slash" Marks the alias as a chat slash command rather than a root CLI command.
cliCommand No string Related root CLI command to suggest for CLI operations, if one exists.

qaRunners reference

Use qaRunners when a plugin contributes one or more transport runners beneath the shared openclaw qa root. Keep this metadata cheap and static; the plugin runtime still owns actual CLI registration through a lightweight qa-runner-api.ts surface that exports matching qaRunnerCliRegistrations. For plugins using the shipped runtime-api.ts contract, that legacy surface remains accepted through 2026-10-01 while authors migrate. An optional adapterFactory exposes the transport to shared QA scenarios without changing the registered command's runner.

Module-backed flow scenarios are an adapter-owned execution form. Set adapterFactory.supportsModuleFlows to true only when every adapter created by that factory implements prepareFlow; QA planning excludes module flows from implementations that do not declare support.

json
{  "qaRunners": [    {      "commandName": "matrix",      "description": "Run the Docker-backed Matrix live QA lane against a disposable homeserver"    }  ]}
Field Required Type What it means
commandName Yes string Subcommand mounted beneath openclaw qa, for example matrix.
description No string Fallback help text used when the shared host needs a stub command.

The adapterFactory id must match commandName. Do not export registrations for commands absent from the manifest.

channelConfigs reference

Use channelConfigs when a channel plugin needs cheap config metadata before runtime loads. Read-only channel setup/status discovery can use this metadata directly for configured external channels when no setup entry is available, or when setup.requiresRuntime: false declares setup runtime unnecessary.

channelConfigs is plugin manifest metadata, not a new top-level user config section. Users still configure channel instances under channels.<channel-id>. OpenClaw reads manifest metadata to decide which plugin owns that configured channel before plugin runtime code executes.

For a channel plugin, configSchema and channelConfigs describe different paths:

  • configSchema validates plugins.entries.<plugin-id>.config
  • channelConfigs.<channel-id>.schema validates channels.<channel-id>

Non-bundled plugins that declare channels[] should also declare matching channelConfigs entries. Without them, OpenClaw can still load the plugin, but cold-path config schema, setup, and Control UI surfaces cannot know the channel-owned option shape or display-only UI hints until plugin runtime executes.

channelConfigs.<channel-id>.commands.nativeCommandsAutoEnabled and nativeSkillsAutoEnabled can declare static auto defaults for command config checks that run before channel runtime loads. Bundled channels can also publish the same defaults through package.json#openclaw.channel.commands alongside their other package-owned channel catalog metadata.

json
{  "channelConfigs": {    "matrix": {      "schema": {        "type": "object",        "additionalProperties": false,        "properties": {          "homeserverUrl": { "type": "string" }        }      },      "uiHints": {        "homeserverUrl": {          "label": "Homeserver URL",          "placeholder": "https://matrix.example.com"        }      },      "label": "Matrix",      "description": "Matrix homeserver connection",      "commands": {        "nativeCommandsAutoEnabled": true,        "nativeSkillsAutoEnabled": true      },      "preferOver": ["matrix-legacy"]    }  }}

Each channel entry can include:

Field Type What it means
schema object JSON Schema for channels.<id>. Required for each declared channel config entry.
uiHints Record<string, object> Optional labels, placeholders, sensitivity, and display-only presentation hints for that channel config section.
label string Channel label merged into picker and inspect surfaces when runtime metadata is not ready.
description string Short channel description for inspect and catalog surfaces.
commands object Static native command and native skill auto-defaults for pre-runtime config checks.
preferOver string[] Legacy or lower-priority plugin ids this channel should outrank in selection surfaces.

Replacing another channel plugin

Use preferOver when your plugin is the preferred owner for a channel id that another plugin can also provide. Common cases are a renamed plugin id, a standalone plugin that supersedes a bundled plugin, or a maintained fork that keeps the same channel id for config compatibility.

json
{  "id": "acme-chat",  "channels": ["chat"],  "channelConfigs": {    "chat": {      "schema": {        "type": "object",        "additionalProperties": false,        "properties": {          "webhookUrl": { "type": "string" }        }      },      "preferOver": ["chat"]    }  }}

When channels.chat is configured, OpenClaw considers both the channel id and the preferred plugin id. If the lower-priority plugin was only selected because it is bundled or enabled by default, OpenClaw disables it in the effective runtime config so one plugin owns the channel and its tools. Explicit user selection still wins: if the user explicitly enables both plugins (via plugins.allow or a material plugins.entries config), OpenClaw preserves that choice and reports duplicate channel/tool diagnostics instead of silently changing the requested plugin set.

Keep preferOver scoped to plugin ids that can really provide the same channel. It is not a general priority field and it does not rename user config keys.
