Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 187 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name executor.

  • Pass

    tools/list returned 29 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 187 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 187 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    8 of 46 parameters have a description (17%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass
    Recently updated

    Updated 2026-11-12T15:42:49.014376Z, within 180 days.

Capabilities

Tools 29

ailang_builtins

List AILANG builtin functions with documentation, grouped by module. `search` filters lines case-insensitively; empty returns everything.

Discovered
ailang_check

Type-check AILANG source. `code` is a whole module; the module line may be omitted or be `module main`. Returns the ai-check JSON report on stdout: check.passed and check.errors (with locations and fixes), and verify: each function's requires/ensures proved with Z3 (verify.results: verified, counterexample with a witness, or inconclusive after 5s per function). Only `pure` functions (or `! {}`) are proved; others report skipped/NOT_PURE. `verification` names the overall result; "unavailable" means this server had no solver, so the code was type-checked only and its contracts were not proved (prove them locally with `ailang verify`).

Discovered
ailang_eval

Evaluate one pure AILANG expression and print it with show(). Builtins are in scope; for stdlib functions (map, filter, ...) use ailang_run with explicit imports.

Discovered
ailang_prompt

Call this FIRST: the AILANG teaching prompt (syntax rules, templates, stdlib map). AILANG is not in your training data the way Python is; code written without this prompt rarely type-checks.

Discovered
ailang_run

Run AILANG source in the hosted sandbox. Entry point is `main`, with no arguments. Only the IO capability is granted (println works; FS, Net, Process, Env and AI are refused by name before the program starts), and the run is killed at the policy timeout. stdout is the program's output; stderr carries the policy decision JSON.

Discovered
ailang_versions

List all AILANG versions the server can answer for.

Discovered
benchmark_run

One run's full result (code, compile_ok, runtime_ok, stdout_ok, cost, tokens).

Discovered
benchmarks_compare

Pairwise model comparison. Output: {a_only_passes, b_only_passes, both, neither}

Discovered
benchmarks_for_model

Where does a given model pass/fail? Optional version filter. Output: {passes: [...], fails_by_category: {...}, total_cost}

Discovered
benchmarks_list

List benchmark suites and runs, optionally filtered to a since_version cutoff.

Discovered
changelog_for_version

What changed in a given release (added/changed/fixed/breaking).

Discovered
design_doc

Full design doc by slug (e.g. "m-agent-mcp-website").

Discovered
design_docs_list

List planned/implemented/rejected design docs, optionally filtered by version. state = "planned" | "implemented" | "rejected" | ""; empty = all.

Discovered
docs_nav

Sidebar tree as JSON. Replaces scraping the Docusaurus sidebar. Version-scoped: snapshot of that release's docs site nav.

Discovered
docs_search

Full-text search across doc Markdown for the given version. Filters server-side on lowercased body + title; returns the top 10 matches, docs pages before archived teaching prompts (prompts/v*.md match almost any query), each as path, title, its first 10 headings and an excerpt around the match: the full page is a docs_nav / example_get away. Whole bodies made one search ~30 KB, too much for a tool result in a listed connector.

Discovered
effects_catalog

All declared effects with capability mapping and the version they appeared in.

Discovered
example_for_concept

Best-fit examples for a free-form concept query ("how do I use effects?"). Filters server-side on why + title; returns up to 5 matches.

Discovered
example_get

Full source + metadata for one example by path.

Discovered
examples_list

Filter examples that pass under for_version, optionally by features/status. features = comma-separated tags ("effects,records"); empty = no filter. status = "passing" | "failing" | ""; empty = passing only.

Discovered
executor_whoami

The signed-in account, as the gate verified it. Served only on the gated /mcp/connect/; the client cannot supply or forge _auth.

Discovered
install_guide

Harness-aware install instructions for AILANG. harness: "claude-code" | "gemini-cli" | "codex-cli" | "manual" | "build-from-source" | "" platform: only meaningful for "manual" (e.g. "darwin-arm64", "linux-amd64"); ignored otherwise Empty harness returns ALL harnesses + the remote_mcp config block.

Discovered
limitations_list

Known limitations (Y-combinator, etc.) optionally filtered by category.

Discovered
onboarding_guide

Stepwise onboarding flow for using AILANG. role: "agent" (AI coding agent flow, default) | "developer" (human dev flow) | "" (returns both) For v1 returns the full guide; client picks the relevant role. v2 may filter on AILANG side once we have proper record-projection helpers.

Discovered
prompt_get

Fetch the canonical teaching prompt for a version. kind = "agent" | "devtools" | "compact" (full prompt = empty).

Discovered
roadmap

What's shipping next, what's been rejected and why.

Discovered
stdlib_module

Full module: exports + signatures + docstrings.

Discovered
stdlib_modules

List stdlib modules available in this AILANG version with one-line summaries.

Discovered
stdlib_search

Find stdlib functions by name, signature, or keyword. Filters the pre-built search index server-side; returns top 20 matches.

Discovered
submit_feedback

Anonymous bug report / feature request / docs gap, queued for human review. Default routing: `public-feedback` inbox (general AILANG). Pass `package="vendor/name"` (e.g. "sunholo/auth") to route to that package's `pkg:vendor/name` inbox where its autonomous agent watches. Categories: bug, feature, docs, limitation. Body limit 10KB, snippet limit 4KB. Optional contact field for follow-up; opaque to the server. Set `auto_dispatch=true` to authorize the package agent to act on your submission immediately (default false — files for human triage; pkg-feedback agent template lands in a separate sprint).
