It allows interaction with Ghidra projects, programs (binaries), functions, symbols, data, memory segments, cross-references, and analysis features. Programs are addressed by their unique identifier within Ghidra (`project:/path/to/file`). - -## General Concepts - -### Request Format - -- Use standard HTTP verbs: - - `GET`: Retrieve resources or lists. - - `POST`: Create new resources. - - `PATCH`: Modify existing resources partially. - - `PUT`: Replace existing resources entirely (Use with caution, `PATCH` is often preferred). - - `DELETE`: Remove resources. -- Request bodies for `POST`, `PUT`, `PATCH` should be JSON (`Content-Type: application/json`). -- Include an optional `X-Request-ID` header with a unique identifier for correlation. - -### Response Format - -All non-error responses are JSON (`Content-Type: application/json`) containing at least the following keys: - -```json -{ - "id": "[correlation identifier]", - "instance": "[instance url]", - "success": true, - "result": Object | Array, - "_links": { // Optional: HATEOAS links - "self": { "href": "/path/to/current/resource" }, - "related_resource": { "href": "/path/to/related" } - // ... other relevant links - } -} -``` - -- `id`: The identifier from the `X-Request-ID` header if provided, or a random opaque identifier otherwise. -- `instance`: The URL of the Ghidra plugin instance that handled the request. -- `success`: Boolean `true` for successful operations. -- `result`: The main data payload, either a single JSON object or an array of objects for lists. -- `_links`: (Optional) Contains HATEOAS-style links to related resources or actions, facilitating discovery. - -#### List Responses - -List results (arrays in `result`) will typically include pagination information and a total count: - -```json -{ - "id": "req-123", - "instance": "http://localhost:1337", - "success": true, - "result": [ ... objects ... ], - "size": 150, // Total number of items matching the query across all pages - "offset": 0, - "limit": 50, - "_links": { - "self": { "href": "/programs/proj:/file.bin/functions?offset=0&limit=50" }, - "next": { "href": "/programs/proj:/file.bin/functions?offset=50&limit=50" }, // Present if more items exist - "prev": { "href": "/programs/proj:/file.bin/functions?offset=0&limit=50" } // Present if not the first page - } -} -``` - -### Error Responses - -Errors use appropriate HTTP status codes (4xx, 5xx) and have a JSON payload with an `error` key: - -```json -{ - "id": "[correlation identifier]", - "instance": "[instance url]", - "success": false, - "error": { - "code": "RESOURCE_NOT_FOUND", // Optional: Machine-readable code - "message": "Descriptive error message" - // Potentially other details like invalid parameters - } -} -``` - -Common HTTP Status Codes: -- `200 OK`: Successful `GET`, `PATCH`, `PUT`, `DELETE`. -- `201 Created`: Successful `POST` resulting in resource creation. -- `204 No Content`: Successful `DELETE` or `PATCH`/`PUT` where no body is returned. -- `400 Bad Request`: Invalid syntax, missing required parameters, invalid data format. -- `401 Unauthorized`: Authentication required or failed (if implemented). -- `403 Forbidden`: Authenticated user lacks permission (if implemented). -- `404 Not Found`: Resource or endpoint does not exist, or query yielded no results. -- `405 Method Not Allowed`: HTTP verb not supported for this endpoint. -- `500 Internal Server Error`: Unexpected error within the Ghidra plugin. - -### Addressing and Searching - -Resources like functions, data, and symbols often exist at specific memory addresses and may have names. The primary identifier for a program is its Ghidra path, e.g., `myproject:/path/to/mybinary.exe`. - -- **By Address:** Use the resource's path with the address (hexadecimal, e.g., `0x401000` or `08000004`). - - Example: `GET /programs/myproject:/mybinary.exe/functions/0x401000` -- **Querying Lists:** List endpoints (e.g., `/functions`, `/symbols`, `/data`) support filtering via query parameters: - - `?addr=[address in hex]`: Find item at a specific address. - - `?name=[full_name]`: Find item(s) with an exact name match (case-sensitive). - - `?name_contains=[substring]`: Find item(s) whose name contains the substring (case-insensitive). - - `?name_matches_regex=[regex]`: Find item(s) whose name matches the Java-compatible regular expression. - -### Pagination - -List endpoints support pagination using query parameters: -- `?offset=[int]`: Number of items to skip (default: 0). -- `?limit=[int]`: Maximum number of items to return (default: implementation-defined, e.g., 100). - -## Meta Endpoints - -### `GET /plugin-version` -Returns the version of the running Ghidra plugin and its API.

-- **Structured responses**: JSON format ensures predictable parsing by AI agents. -- **HATEOAS Links**: `_links` allow agents to discover available actions and related resources without hardcoding paths. -- **Address and Name Resolution**: Key elements like functions and symbols are addressable by both memory address and name where applicable. -- **Explicit Operations**: Actions like decompilation, disassembly, and analysis are distinct endpoints. -- **Pagination & Filtering**: Essential for handling potentially large datasets (symbols, functions, xrefs, disassembly). -- **Clear Error Reporting**: `success: false` and the `error` object provide actionable feedback. -- **No Injected Summaries**: The API should return raw or structured Ghidra data, leaving interpretation and summarization to the AI agent. diff --git a/MCP_BRIDGE_API.md b/MCP_BRIDGE_API.md index 39f98ba..a07711f 100644 --- a/MCP_BRIDGE_API.md +++ b/MCP_BRIDGE_API.md @@ -6,6 +6,9 @@ This document describes the MCP tools and resources exposed by the GhydraMCP bri ## Core Concepts -
