# GhydraMCP Ghidra Plugin HTTP API v1
## Overview
This API provides a Hypermedia-driven interface (HATEOAS) to interact with Ghidra's CodeBrowser, enabling AI-driven and automated reverse engineering workflows. 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<Object>,
"_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. Essential for compatibility checks by clients like the MCP bridge.
```json
{
"id": "req-meta-ver",
"instance": "http://localhost:1337",
"success": true,
"result": {
"plugin_version": "v1.4.0", // Example plugin build version
"api_version": 1 // Ordinal API version
},
"_links": {
"self": { "href": "/plugin-version" }
}
}
```
## Resource Types
Base path for all program-specific resources: `/programs/{program_id}` where `program_id` is the URL-encoded Ghidra identifier (e.g., `myproject%3A%2Fpath%2Fto%2Fmybinary.exe`).
### 1. Projects
Represents Ghidra projects, containers for programs.
- **`GET /projects`**: List all available Ghidra projects.
- **`POST /projects`**: Create a new Ghidra project. Request body should specify `name` and optionally `directory`.
- **`GET /projects/{project_name}`**: Get details about a specific project (e.g., location, list of open programs within it via links).
### 2. Programs
Represents individual binaries loaded in Ghidra projects.
- **`GET /programs`**: List all programs across all projects. Can be filtered by project (`?project={project_name}`).
- **`POST /programs`**: Load/import a new binary into a specified project. Request body needs `project_name`, `file_path`, and optionally `language_id`, `compiler_spec_id`, and loader options. Returns the newly created program resource details upon successful import and analysis (which might take time).
- **`GET /programs/{program_id}`**: Get metadata for a specific program (e.g., name, architecture, memory layout, analysis status).
```json
// Example Response Fragment for GET /programs/myproject%3A%2Fmybinary.exe
"result": {
"program_id": "myproject:/mybinary.exe",
"name": "mybinary.exe",
"project": "myproject",
"language_id": "x86:LE:64:default",
"compiler_spec_id": "gcc",
"image_base": "0x400000",
"memory_size": 1048576,
"is_open": true,
"analysis_complete": true
// ... other metadata
},
"_links": {
"self": { "href": "/programs/myproject%3A%2Fmybinary.exe" },
"project": { "href": "/projects/myproject" },
"functions": { "href": "/programs/myproject%3A%2Fmybinary.exe/functions" },
"symbols": { "href": "/programs/myproject%3A%2Fmybinary.exe/symbols" },
"data": { "href": "/programs/myproject%3A%2Fmybinary.exe/data" },
"segments": { "href": "/programs/myproject%3A%2Fmybinary.exe/segments" },
"memory": { "href": "/programs/myproject%3A%2Fmybinary.exe/memory" },
"xrefs": { "href": "/programs/myproject%3A%2Fmybinary.exe/xrefs" },
"analysis": { "href": "/programs/myproject%3A%2Fmybinary.exe/analysis" }
// Potentially actions like "close", "analyze"
}
```
- **`DELETE /programs/{program_id}`**: Close and potentially remove a program from its project (behavior depends on Ghidra state).
### 3. Functions
Represents functions within a program. Base path: `/programs/{program_id}/functions`.
- **`GET /functions`**: List functions. Supports searching (by name/address/regex) and pagination.
```json
// Example Response Fragment
"result": [

- **`PATCH /functions/{address}/variables/{variable_name}`**: Modify a local variable (rename, change type). Requires `name` and/or `type` in the payload.
### 4. Symbols & Labels
Represents named locations (functions, data, labels). Base path: `/programs/{program_id}/symbols`.
- **`GET /symbols`**: List all symbols in the program. Supports searching (by name/address/regex) and pagination. Can filter by type (`?type=function`, `?type=data`, `?type=label`).
- **`POST /symbols`**: Create or rename a symbol at a specific address. Requires `address` and `name` in the payload. If a symbol exists, it's renamed; otherwise, a new label is created.
- **`GET /symbols/{address}`**: Get details of the symbol at the specified address.
- **`PATCH /symbols/{address}`**: Modify properties of the symbol (e.g., set as primary, change namespace). Payload specifies changes.
- **`DELETE /symbols/{address}`**: Remove the symbol at the specified address.
### 5. Data
Represents defined data items in memory. Base path: `/programs/{program_id}/data`.
- **`GET /data`**: List defined data items. Supports searching (by name/address/regex) and pagination. Can filter by type (`?type=string`, `?type=dword`, etc.).
- **`POST /data`**: Define a new data item. Requires `address`, `type`, and optionally `size` or `length` in the payload.
- **`GET /data/{address}`**: Get details of the data item at the specified address (type, size, value representation).
- **`PATCH /data/{address}`**: Modify a data item (e.g., change `name`, `type`, `comment`). Payload specifies changes.
- **`DELETE /data/{address}`**: Undefine the data item at the specified address.
### 6. Memory Segments
Represents memory blocks/sections defined in the program. Base path: `/programs/{program_id}/segments`.
- **`GET /segments`**: List all memory segments (e.g., `.text`, `.data`, `.bss`).
- **`GET /segments/{segment_name}`**: Get details for a specific segment (address range, permissions, size).
### 7. Memory Access
Provides raw memory access. Base path: `/programs/{program_id}/memory`.
- **`GET /memory/{address}`**: Read bytes from memory.
- Query Parameters:
- `?length=[bytes]`: Number of bytes to read (required, max limit applies).
- `?format=[hex|base64|string]`: How to encode the returned bytes (default: hex).
```json
// Example Response Fragment for GET /programs/proj%3A%2Ffile.bin/memory/0x402000?length=16&format=hex
"result": {
"address": "0x402000",
"length": 16,
"format": "hex",
"bytes": "48656C6C6F20576F726C642100000000" // "Hello World!...."
}
```
- **`PATCH /memory/{address}`**: Write bytes to memory. Requires `bytes` (in specified `format`) and `format` in the payload. Use with extreme caution.
### 8. Cross-References (XRefs)
Provides information about references to/from addresses. Base path: `/programs/{program_id}/xrefs`.
- **`GET /xrefs`**: Search for cross-references. Supports pagination.
- Query Parameters (at least one required):
- `?to_addr=[address]`: Find references *to* this address.
- `?from_addr=[address]`: Find references *from* this address or within the function/data at this address.
- `?type=[CALL|READ|WRITE|DATA|POINTER|...]`: Filter by reference type.
- **`GET /functions/{address}/xrefs`**: Convenience endpoint, equivalent to `GET /xrefs?to_addr={address}` and potentially `GET /xrefs?from_addr={address}` combined or linked.
### 9. Analysis
Provides access to Ghidra's analysis results. Base path: `/programs/{program_id}/analysis`.
- **`GET /analysis/callgraph`**: Retrieve the function call graph (potentially filtered or paginated). Format might be nodes/edges JSON or a standard graph format like DOT.
- **`GET /analysis/dataflow/{address}`**: Perform data flow analysis starting from a specific address or instruction. Requires parameters specifying forward/backward, context, etc. (Details TBD).
- **`POST /analysis/analyze`**: Trigger a full or partial re-analysis of the program.
## Design Considerations for AI Usage
- **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.

## Core Concepts
- Each Ghidra instance runs its own HTTP server (default port 8192)
- The bridge discovers and manages multiple Ghidra instances
- Programs are addressed by their unique identifier within Ghidra (`project:/path/to/file`).
- The primary identifier for a program is its Ghidra path, e.g., `myproject:/path/to/mybinary.exe`.
- The bridge must keep track of which plugin host and port has which project & file and route accordingly
- Tools are organized by resource type (programs, functions, data, etc.)
- Consistent response format with success/error indicators

STRICT HATEOAS COMPLIANCE REQUIREMENTS:
All endpoints must follow these requirements:
1. Include success, id, instance, and result fields in response
2. Include _links with at least a "self" link
3. Use consistent result structures for the same resource types
4. Follow standard RESTful URL patterns (e.g., /programs/current/functions/{address})
5. Include pagination metadata (offset, limit, size) for collection endpoints
Endpoints requiring HATEOAS updates:
- /classes: Missing _links field
- /instances: Missing _links field
- /segments: Result should be a list, not an object
- /programs/current/functions/{address}/decompile: Result should include "decompiled" field
- /programs/current/functions/{address}/disassembly: Result should include "instructions" list
- /programs/current/functions/by-name/{name}/variables: Result should include "variables" and "function" fields
This test suite enforces strict HATEOAS compliance with no backward compatibility.
