github_codespaces_get_repo_secret

Instructions

Implementation Reference

• src/tools/codespaces.ts:302-304 (handler)

  The handler function that executes the 'github_codespaces_get_repo_secret' tool logic - makes a GET request to GitHub's API to fetch a repository secret.

  handler: async (args: Record<string, any>) => {
    return githubRequest("GET", `/repos/${args.owner}/${args.repo}/codespaces/secrets/${args.secret_name}`, undefined, undefined);
  },

• src/tools/codespaces.ts:297-301 (schema)

  Input schema defining the required parameters: owner (string), repo (string), and secret_name (string).

  inputSchema: z.object({
    owner: z.string().describe("owner"),
    repo: z.string().describe("repo"),
    secret_name: z.string().describe("secret_name")
  }),

• src/index.ts:110-130 (registration)

  Tool registration in the MCP server - tools are registered via server.tool() using their name, description, schema, and handler.

  for (const tool of allTools) {
    server.tool(
      tool.name,
      tool.description,
      tool.inputSchema.shape as any,
      async (args: any) => {
        try {
          const result = await tool.handler(args as any);
          return {
            content: [{ type: "text" as const, text: JSON.stringify(result, null, 2) }],
          };
        } catch (err) {
          const message = err instanceof Error ? err.message : String(err);
          return {
            content: [{ type: "text" as const, text: `Error: ${message}` }],
            isError: true,
          };
        }
      }
    );
  }

• src/tools/codespaces.ts:294-305 (registration)

  Tool definition object containing name, description, inputSchema, and handler - part of the codespacesTools array.

  {
    name: "github_codespaces_get_repo_secret",
    description: "Get a repository secret",
    inputSchema: z.object({
      owner: z.string().describe("owner"),
      repo: z.string().describe("repo"),
      secret_name: z.string().describe("secret_name")
    }),
    handler: async (args: Record<string, any>) => {
      return githubRequest("GET", `/repos/${args.owner}/${args.repo}/codespaces/secrets/${args.secret_name}`, 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>;
  }
