Category Security
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. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, but returns a challenge with no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0
- Schema blocked by authentication: the endpoint requires auth we don't have to read it. See how to fix → Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Tool Safety0
- Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Capabilities0
- Capabilities blocked by authentication: the endpoint requires auth we don't have to read them. See how to fix → Unverified
Unverified: 6 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm. Claim this server and supply a read-only token to verify it and lift the score.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

How do I install the TheLeaf Threat Observatory MCP server?
TheLeaf Threat Observatory is a hosted endpoint at https://observatory.theleaf.ai/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.

What is the TheLeaf Threat Observatory MCP server?
TheLeaf Threat Observatory is an MCP server listed in the public MCP registry as ai.theleaf.observatory/threat-observatory. Read-only honeypot observations and evidence. Invite-only API key; request access on our website. This page covers its hosted endpoint (https://observatory.theleaf.ai/mcp).
Is the TheLeaf Threat Observatory MCP server safe to use?
TheLeaf Threat Observatory scores 33 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 TheLeaf Threat Observatory MCP server expose?
TheLeaf Threat Observatory exposes 6 tools: search_observations, lookup_observed_ip, get_activity_summary, get_session_timeline, get_sensor_coverage, get_observation_evidence. Their descriptions and schemas cost roughly 422 tokens of context every time the server is loaded.
Does the TheLeaf Threat Observatory MCP server require authentication?
Yes. TheLeaf Threat Observatory asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the TheLeaf Threat Observatory MCP server still maintained?
TheLeaf Threat Observatory 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.
