hf-mcp 0.2.8

Standalone Hack Forums MCP launch surface

hf-mcp

hf-mcp is a standalone MCP server package for the Hack Forums API v2.

Current release line: 0.2.8.

Install

pip install hf-mcp

Entrypoints

• hf-mcp (aliases hf-mcp serve)
• python -m hf_mcp
• hf-mcp setup init
• hf-mcp auth bootstrap
• hf-mcp doctor
• hf-mcp serve

Desktop MCP clients

Desktop client wiring is first-class and documented in docs/client_integration.md, including:

• direct command launch (hf-mcp serve)
• module launch (python -m hf_mcp serve)
• virtualenv/conda launch forms
• native Windows Python launch
• Windows desktop client to WSL bridge examples (including Claude Desktop style)

Default local paths

• config: ~/.config/hf_mcp/config.yaml
• token store: ~/.config/hf_mcp/token.json

Path overrides:

• HF_MCP_CONFIG for config path
• HF_MCP_ENV_FILE for explicit .env path
• HF_MCP_TOKEN_PATH for token path (unless YAML token_path is set)

Full precedence and policy split are documented in docs/configuration.md.

Read output defaults

Read tools default to human-readable summaries while keeping canonical JSON for scripts.

• default mode: readable
• per-call override: output_mode (readable, structured, raw)
• additive raw payload toggle: include_raw_payload

Compatibility contract for read tools:

• structuredContent always carries normalized/canonical JSON for automation.
• output_mode="structured" keeps script-friendly structuredContent with terse text.
• raw payload remains available as an additive JSON resource when output_mode="raw" or include_raw_payload=true.

See docs/configuration.md for read_output_defaults config and docs/examples.md for concrete request/response examples.

Automation usage

For automated clients, call read tools with output_mode="structured" when you only need normalized fields, or output_mode="raw" / include_raw_payload=true when you also need the exact upstream HF API payload as an additive MCP resource.

Example:

{
  "tool": "posts.read",
  "arguments": {
    "tid": 6324346,
    "per_page": 1,
    "include_post_body": true,
    "output_mode": "raw",
    "include_raw_payload": true
  }
}

Expected protocol shape:

{
  "content": [
    {"type": "text", "text": "posts.read returned 1 row(s)."},
    {"type": "resource", "resource": {"uri": "hf-mcp://raw/posts.read", "mimeType": "application/json"}}
  ],
  "structuredContent": {
    "posts": [
      {
        "pid": "62946370",
        "tid": "6324346",
        "subject": "The HF API MCP server",
        "message": "[size=xx-large][align=center][css=68]HF MCP Is Live..."
      }
    ]
  }
}

Quick start

pip install hf-mcp
hf-mcp setup init
hf-mcp auth bootstrap
hf-mcp doctor
hf-mcp serve

Before auth bootstrap, create your own Hack Forums API developer app in the HF user control panel. You can use the hosted callback https://cortalabs.github.io/hf_mcp/oauth_callback.html for HF_MCP_EXTERNAL_REDIRECT_URI, or host docs/oauth_callback.html yourself and use that HTTPS URL instead.

Module launch equivalent:

python -m hf_mcp serve

Safety and release posture

• Read paths and guarded writes are documented publicly, with fail-closed behavior for concrete writes via confirm_live=true.
• Concrete write helpers currently exposed are threads.create, posts.reply, and Bytes write helpers (bytes.transfer, bytes.deposit, bytes.withdraw, bytes.bump) with repaired argument contracts.
• scheduled_at on draft artifacts is metadata for operator workflow only; hf-mcp does not ship a scheduler/queue that auto-executes future writes.
• HF API quote/entity canonicalization on live writes is treated as expected security/sanitization behavior, not a bypass target.
• Manual live validation in this wave is intentionally narrower: replies only on TID 6083735 plus at most one threads.create in FID 375; no Bytes live writes.
• Placeholder writes remain out of scope in this wave (contracts.write, sigmarket.write, admin.high_risk.write).
• Detailed release-boundary and limitation truth is owned by docs/export_boundary.md.
