| 2 | * MCP tool handlers — read-only v1 set. | |
| 3 | * | |
| 4 | * Each handler returns either a string (auto-wrapped to text content) | |
| 5 | * or the full MCP `{content: [...]}` shape. Errors throw `McpError` from | |
| 6 | * `mcp.ts` so the router can surface them as JSON-RPC -32xxx codes. | |
| 7 | * | |
| 8 | * Tool surface (v1, all read-only): | |
| 9 | * - gluecron_repo_search — search public repos by keyword | |
| 10 | * - gluecron_repo_read_file — read a file from a repo at a ref | |
| 11 | * - gluecron_repo_list_issues — list open issues for a repo | |
| 12 | * - gluecron_repo_explain_codebase — return cached AI explanation | |
| 13 | * | |
| 14 | * v2 will add write tools (create_issue, post_comment, run_workflow) | |
| 15 | * gated on `userId` + write-access on the target repo. | |
