GitLab ACTION
Resolve Merge Request Thread
Mark a merge request thread as resolved, or reopen a resolved one by setting Resolved to
false. Use this after acting on a piece of review feedback — resolving threads is what clears a merge request's blocking_discussions_resolved flag so it can merge. Get the Discussion ID from List Merge Request Discussions (set its Only Unresolved to true to see just the threads still open). Only threads that are resolvable can be resolved: plain comments on the merge request as a whole are not, and GitLab rejects the attempt. See the documentation- Action

IMPLEMENTATION
Call this tool
Connect a user's GitLab account once, then configure and run Resolve Merge Request Thread from your backend or agent.
import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "gitlab-resolve-merge-request-thread",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
gitlab: { authProvisionId: "apn_xxxxxxx" },
projectId: "Project",
mergeRequestIid: 10,
},
})
console.log(result)curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \
-H "Content-Type: application/json" \
-H "X-PD-Environment: production" \
-H "Authorization: Bearer {access_token}" \

}'// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(
new URL("https://remote.mcp.pipedream.net/v3"),
{
requestInit: {
headers: {
Authorization: `Bearer ${accessToken}`,
"x-pd-project-id": "{project_id}",

},
},
},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
name: "gitlab-resolve-merge-request-thread",
arguments: {
projectId: "Project",
mergeRequestIid: 10,
},
})SCHEMA
Inputs
Pipedream supplies the connected account. Your application provides the operation-specific values below. Dynamic inputs are resolved against that user's account.
| Property | Type | Description |
|---|---|---|
projectId Project | string | The project, given either as its path — group/project or group/subgroup/project, e.g. backend/payments — or as its numeric project ID. The path is what appears in the project URL and is usually what a user will name, so prefer it. A pasted GitLab URL also works. Use List Projects to find the path if you only know part of the name. Required |
mergeRequestIid Merge Request IID | integer | The merge request's internal ID — the !N shown in the GitLab UI and the number at the end of the merge request URL. This is not the id field, which is a much larger instance-wide number; passing id here returns a 404. Use List Merge Requests or Search Merge Requests to resolve the IID from a title, branch or author. Required |
discussionId Discussion ID | string | The ID of a merge request thread — a 40-character hex string. Use List Merge Request Discussions to find it. Required |
resolved Resolved | boolean | true (the default) resolves the thread; false reopens a thread that was previously resolved. Optional |
REFERENCE
Tool details
Behavior hints are published with the component in the Pipedream registry and surface as MCP tool annotations, so an agent can reason about a tool before it calls it.
