Yasin-MCP

Standalone AI/Agent-facing MCP (Model Context Protocol) access and integration layer for the Yasin ecosystem.

Status

Yasin-MCP roadmap Stages 1–15 are complete on the controlled-integration path. Master #96 is the roadmap closure gate. Stage 15 is the final planned roadmap stage; no planned Stage 16 remains.

The repository has reached a stable v1.0.0 release for the currently verified scope. The release is suitable for controlled integration. This classification does not claim a public package publication or unrestricted production deployment.

Roadmap completion evidence

  • Stage 11 / #97: merged.

  • Stage 12 / #98 → PR #103: merged.

  • Stage 13 / #99 → PR #104: merged; live ecosystem-compatible MCP client path verified over authenticated Streamable HTTP, including identity propagation, governance, approval, execution, audit correlation, and fail-closed malformed context handling.

  • Stage 14 / #100 → PR #105 and lifecycle-resilience PR #106: merged; bounded concurrency, deterministic lifecycle/isolation coverage, stress behavior, cleanup, slot recovery, and post-stress usability are covered.

  • Stage 15 / #101: final release, reproducibility, compatibility, documentation, transport, security, and roadmap-closure verification.

Current verification

The latest controlled Termux verification completed successfully:

  • 402 tests passed

  • 2 tests skipped

  • Native Termux environment verified with Python 3.14.6

  • cryptography 50.0.1 imported successfully in the verified environment

  • Operations subprocess transport verified using a Termux-compatible Python gateway invocation

See docs/RELEASE_READINESS.md and docs/compatibility/YASIN_MCP_TERMUX_COMPATIBILITY.md for the detailed assessment and Termux evidence.

Architecture boundary

Yasin-MCP does not replace YASIN-DOCS, Yasin-Core, Yasin-Agent, Yasin-AI, YasinHub, YasinCLI, or Yasin-Operations. It is an access/integration layer.

  • MCP capabilities are read-only at the product surface unless an explicitly governed reference capability is present for testing governance behavior.

  • No generic shell passthrough or arbitrary command execution is exposed.

  • Integrations use public APIs, SDKs, contracts, or explicit adapters; no private cross-repository imports are required.

  • Tool execution crosses the centralized GovernanceGate for authentication, approval, policy, audit, and bounded-concurrency enforcement.

  • External/untrusted content is represented using explicit evidence/trust boundaries and is not treated as instructions.

  • Yasin-Core v3.4.0 shared observation contracts are spoken through the dependency-free translators in src/yasin_mcp/compat/ — see docs/CORE_CONTRACTS.md. Yasin-MCP owns no lifecycle; YasinHub remains the sole Control Plane.

Tool surface

Always available:

  • yasin_docs_* — documentation access

  • yasin_github_* — read-only GitHub ecosystem access

  • yasin_registry_* — project/dependency registry access

  • yasin_gov_* — governance reference capabilities used to exercise policy/approval boundaries

Conditionally available:

  • yasin_operations_* — registered only when the yasin-operations executable is available on PATH.

The capability surface is versioned independently through CAPABILITY_SURFACE_VERSION.

Evidence model

Responses that report ecosystem state use one of:

  • CONFIRMED — directly observed from a live authoritative source

  • TARGET — documented intent/architecture, not verified live

  • PROPOSED — suggestion or plan, not implemented

  • UNRESOLVED — could not be determined; never present this as fact

Security and governance

Yasin-MCP treats documentation, GitHub content, registry content, and Operations output as external/untrusted data. Structural trust/evidence envelopes preserve the distinction between retrieved data and instructions.

The governance path is centralized and fail-closed. Authentication is established at the boundary; approval is explicit for mutation-risk reference capabilities; policy decisions are audited; structured errors are used at public boundaries; and configured concurrency is bounded.

Transport

stdio

The standard MCP stdio transport is supported and covered by the repository's live client/CLI validation surface.

Streamable HTTP

Remote transport is implemented through an ASGI application and supports bearer authentication. Stage 13 provides live local verification using the official MCP Python client, with a real ClientSession, Streamable HTTP connection, authentication, context propagation, governance, approval, execution, and audit correlation.

Remote deployments require TLS unless remote_allow_insecure_http is explicitly enabled for local testing.

Packaging and supported runtimes

pyproject.toml declares:

  • package version: 0.1.0 (the package metadata version remains independent from the Git release tag)

  • requires-python = ">=3.10"

  • mcp>=2,<3

  • PyYAML>=6,<7

CI validates Python 3.10, 3.11, and 3.12 with Ruff, Mypy, Bandit, and pytest.

Termux

Native Termux compatibility is verified for the current repository state. The verified environment is Android/Termux on aarch64 with Python 3.14.6. The repository includes a dedicated scripts/termux-test.sh compatibility check and the Operations adapter supports the Termux Python-gateway invocation model.

Termux verification is an environment-specific compatibility result; it does not change the declared general CPython requirement above or imply that every Android/Termux package combination is supported.

Development

pip install -e ".[dev]"
pytest

Final roadmap rule

Master #96 defines the current five-issue completion roadmap. Stage 15 is its final planned stage. Future maintenance or genuinely new product features may be added later, but omitted roadmap work must not be hidden under a new Stage 16.

Native Termux compatibility is explicitly documented as verified for the current repository state based on the controlled test evidence above.

Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

D1.8/5.0

Scored across 22 tools

Disambiguation4/5

The domain prefixes make docs, GitHub, registry, and governance tools easy to separate, and most operations target a clear resource. However, yasin_docs_list_architecture and yasin_docs_get_project_architecture are easy to confuse, and yasin_docs_search overlaps somewhat with yasin_docs_list_documents.

Naming Consistency4/5

Nearly all tools follow a yasin_<domain>_<verb>_<resource> pattern with consistent list_/get_ prefixes. Exceptions like yasin_docs_search, yasin_gov_ping_low_risk, and yasin_gov_apply_mark break the verb convention, though the domain prefixes keep the overall scheme readable.

Tool Count3/5

At 22 tools, the server sits in the heavy range and spans four distinct domains, making the surface feel larger than necessary. It is not extreme, but several similar read-only GitHub and docs tools make the count feel slightly bloated.

Completeness3/5

The server covers a broad read-only surface for docs, GitHub, registry, and governance, but it lacks write/update/delete operations and some get-by-id counterparts for list-only resources like commits and workflow runs. This leaves notable gaps if the server is intended to support end-to-end documentation or repository workflows.
