github_apps_delete_installation

Instructions

Implementation Reference

• src/tools/apps.ts:114-116 (handler)

  The handler function that executes the tool logic: sends a DELETE request to /app/installations/{installation_id} to delete a GitHub App installation.

  handler: async (args: Record<string, any>) => {
    return githubRequest("DELETE", `/app/installations/${args.installation_id}`, undefined, undefined);
  },

• src/tools/apps.ts:111-113 (schema)

  Input schema defining that the tool requires an installation_id string parameter.

  inputSchema: z.object({
    installation_id: z.string().describe("installation_id")
  }),

• src/tools/apps.ts:108-117 (registration)

  The tool is defined as an entry in the appsTools array in src/tools/apps.ts. It is re-exported via src/tools/index.ts and registered with the MCP server in src/index.ts.

  {
    name: "github_apps_delete_installation",
    description: "Delete an installation for the authenticated app",
    inputSchema: z.object({
      installation_id: z.string().describe("installation_id")
    }),
    handler: async (args: Record<string, any>) => {
      return githubRequest("DELETE", `/app/installations/${args.installation_id}`, undefined, undefined);
    },
  },

• src/client.ts:9-59 (helper)

  The githubRequest helper function used by the handler to make authenticated HTTP requests to the GitHub API.

  export async function githubRequest<T>(
    method: string,
    path: string,
    body?: Record<string, unknown>,
    params?: Record<string, string | number | boolean | string[] | undefined>
  ): Promise<T> {
    const url = new URL(`${BASE_URL}${path}`);
  
    if (params) {
      for (const [key, value] of Object.entries(params)) {
        if (value === undefined || value === null || value === "") continue;
        if (Array.isArray(value)) {
          url.searchParams.set(key, value.join(","));
        } else {
          url.searchParams.set(key, String(value));
        }
      }
    }
  
    const headers: Record<string, string> = {
      Authorization: `Bearer ${getToken()}`,
      Accept: "application/vnd.github+json",
      "X-GitHub-Api-Version": "2022-11-28",
      "User-Agent": "github-mcp/1.0.0",
    };
  
    if (body) {
      headers["Content-Type"] = "application/json";
    }
  
    const res = await fetch(url.toString(), {
      method,
      headers,
      body: body ? JSON.stringify(body) : undefined,
    });
  
    if (!res.ok) {
      const text = await res.text().catch(() => "");
      let detail = text;
      try {
        const json = JSON.parse(text);
        detail = json.message || text;
        if (json.errors) detail += ` -- ${JSON.stringify(json.errors)}`;
      } catch {}
      throw new Error(`GitHub API error ${res.status}: ${detail}`);
    }
  
    if (res.status === 204) return {} as T;
  
    return res.json() as Promise<T>;
  }
