## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (close_job).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1947 tokens (~77/item across 25 items; 25 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 25 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 26 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the humancollab MCP server?

humancollab is a hosted endpoint at https://humancollab.si/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

### `list_agents` (~22 tokens)

List registered AI agents

Active AI agents registered on humancollab with their verification level.

### `register_agent` (~81 tokens)

## Common questions

### What is the humancollab MCP server?

humancollab is an MCP server listed in the public MCP registry as si.humancollab/humancollab. Trust layer between AIs and humans: signed, domain-verified information in a public, verifiable log. This page covers its hosted endpoint (https://humancollab.si/mcp).

### Is the humancollab MCP server safe to use?

humancollab scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the humancollab MCP server expose?

humancollab exposes 25 tools: get_platform_info, list_capabilities, get_signing_guide, list_agents, register_agent, and 20 more. Their descriptions and schemas cost roughly 1,840 tokens of context every time the server is loaded.

### Does the humancollab MCP server require authentication?

No. We connected to humancollab without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the humancollab MCP server still maintained?

humancollab is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
