Anthropic 平台文档（英文全量）

You can mount a GitHub repository to your session sandbox and connect to the GitHub MCP for making pull requests.

GitHub repositories are cached, so future sessions that use the same repository start faster.

Managed Agents API requests require the managed-agents-2026-04-01 beta header, except memory store endpoints, which use agent-memory-2026-07-22 instead. The SDK sets the correct beta header automatically. See Beta headers.

GitHub MCP and session resources

First, create an agent that declares the GitHub MCP server. The agent definition holds the server URL but no authentication token:

bash

agent_id=$(curl -fsS https://api.anthropic.com/v1/agents \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "anthropic-beta: managed-agents-2026-04-01" \
  -H "content-type: application/json" \
  --data @- <<JSON | jq -r '.id'
{
  "name": "Code Reviewer",
  "model": "claude-opus-5",
  "system": "You are a code review assistant with access to GitHub.",
  "mcp_servers": [
    {
      "type": "url",
      "name": "github",
      "url": "https://api.githubcopilot.com/mcp/"
    }
  ],
  "tools": [
    {"type": "agent_toolset_20260401"},
    {
      "type": "mcp_toolset",
      "mcp_server_name": "github"
    }
  ]
}
JSON
)

```bash CLI
ant apply code-reviewer.md
```

  ```markdown

  mcp_servers:

Then create a session that mounts the GitHub repository:

bash

  --data @- <<JSON | jq -r '.id'
{
  "agent": "$agent_id",
  "environment_id": "$environment_id",
  "resources": [
    {
      "type": "github_repository",
      "url": "https://github.com/org/repo",
      "mount_path": "/workspace/repo",
      "authorization_token": "ghp_your_github_token"
    }
  ]
}
JSON
)

bash

SESSION_ID=$(ant beta:sessions create \
  --agent "$AGENT_ID" \
  --environment-id "$ENVIRONMENT_ID" \
  --transform id --raw-output <<'EOF'
resources:
  - type: github_repository

A github_repository resource accepts the following fields:

Field	Description
`type`	Required. Must be `"github_repository"`.
`url`	Required. The repository's HTTPS URL in the form `https://github.com/<owner>/<repo>`, without a `.git` suffix. Other forms, including SSH URLs, are rejected with an `invalid_request_error`.
`authorization_token`	Required. The GitHub token used to clone the repository. It is not echoed in API responses. See Token permissions.
