Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
Provenance & Transparency100

Schema Quality & AI Usability79
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 2968 tokens (~76/item across 39 items; 37 tools + 2 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 37 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 39 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 2 categories
Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.
How do I install the Hatun MCP - Governed Agent Gateway server?
Hatun MCP - Governed Agent Gateway runs locally as a container image, launched with docker run --rm -i -e HATUN_MCP_DISABLE_DYNAMIC -e HATUN_MCP_SIGNING_KEY ghcr.io/szl-holdings/hatun-mcp:1.0.1. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

Background: How many MCP packages publish verified provenance →
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 →

szl_lambda_quorum ~354
Governance-critical Λ verdict under a Byzantine n>=3f+1 quorum (n=5, f=1). Fans the action out to the five SZL organs' policy/verdict routes, collects each organ's verdict, and decides only if >= 2f+1 (=3) reachable organs AGREE and >= 3f+1 (=4) organs are reachable. Each organ's contribution mints a Khipu receipt; the participating receipts are BLS-aggregated into one signature. The full quorum tally + aggregate ride in `governance.quorum`. HONEST: each organ's reachability is captured from the real HTTP status; any organ whose policy route is not live contributes an honest miss and the degradation is disclosed. OUROBOROS LOOP (in-code, receipt-closed). The organ fan-out — the repo's actual multi-step orchestration path — runs inside `hatun_mcp.loop.run_bounded_loop`: a HARD step budget (env `HATUN_MCP_LOOP_MAX_STEPS`, safe default 12), per-step trace entries, and an HONEST exit reason (`converged` | `budget_exhausted` | `error`, never fabricate convergence). The trace rides in `governance.loop` and in the top-level Khipu receipt detail. Default behavior is unchanged: the default 5-organ set is well under the budget, so it always exits `converged`. Doctrine: "bounded, terminating, receipt-closed" (Λ = Conjecture 1, never a theorem).

What is the Hatun MCP - Governed Agent Gateway server?
Hatun MCP - Governed Agent Gateway is listed in the public MCP registry as io.github.szl-holdings/hatun-mcp. Governed MCP gateway: policy gate on every tool call, hash-chained DSSE receipt on every result. This page covers its container image (ghcr.io/szl-holdings/hatun-mcp).
Is the Hatun MCP - Governed Agent Gateway server safe to use?
Hatun MCP - Governed Agent Gateway scores 50 out of 100 on VerifyMCP. Its build provenance is signed and verified. 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 Hatun MCP - Governed Agent Gateway server expose?
Hatun MCP - Governed Agent Gateway exposes 37 tools: szl_a11oy_code_chat, szl_killinchu_detect, szl_killinchu_cue, szl_immune_scan, szl_companion_reason, and 32 more. Their descriptions and schemas cost roughly 2,829 tokens of context every time the server is loaded.
Is the Hatun MCP - Governed Agent Gateway server still maintained?
Hatun MCP - Governed Agent Gateway is still listed as active in the MCP registry. We last reached this channel on 1 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Hatun MCP - Governed Agent Gateway server under?
Hatun MCP - Governed Agent Gateway declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
