概览

AI 生成的概览

一个本地 stdio MCP 服务器，为助手提供基于 Cargo、rustc 与 Rust Analyzer 的有界 Rust 正确性工具，且不写入工作区源码。

可以做什么: 运行有界的 Cargo check、Clippy、测试、文档或完整门禁，并用 profile 与 verify 矩阵比较构建证据，同时审计源码静态问题、解释宏展开、trait 约束与 cfg 启用情况。在 crates.io 上核对 crate 及精确版本，并从缓存、本地源码或 docs.rs 解析对应版本文档。借助 Rust Analyzer 导航代码：悬停信息、定义、引用、实现、符号、调用层级与 API 签名。生成经过验证的重命名与重构编辑包，并在服务器自有暂存区中创建绑定修订的变更集或编译器驱动的修复候选，而不写入工作区。以显式门禁和预算驱动类型化意图完成变更与验证。
适用场景: 适合助手处理 Rust 项目、需要基于编译器和分析器的实证而非猜测时使用：检查构建、诊断失败、了解不熟悉的 crate，或准备供人工审阅的重命名与重构。适合希望获得验证结果和编辑包、但自己动手应用改动的开发者。
运行要求: 以本地二进制通过 stdio 运行；可用 Cargo 从 crates.io 安装（需 Rust 1.88.0 或更新版本），或使用 Linux x86_64、macOS arm64、Windows x86_64 的预编译包。验证需要 Rust 工具链与 Cargo，查询 crates.io 和 docs.rs 需要网络访问。默认仅授权当前目录，可用 --allow-root 添加根目录。可通过 AGZ_RUST_MCP_* 环境变量和 --config TOML 文件调整行为。

安装前请注意

它不修改工作区源码，但不是操作系统沙箱：Cargo 构建脚本、测试、过程宏、本地 rustdoc 以及启用的 Rust Analyzer 工作区代码会以服务器用户的权限执行，若需要该隔离边界请使用容器或系统沙箱。Cargo 操作可能耗时较长，受超时与编译预算限制。本地遥测默认开启，记录有界活动但不含提示词或源码。重命名与重构工具只生成编辑包，不会自动应用。

安装

AGZ Rust MCP

English | Türkçe

An AGZ Yazılım product. agz-rust-mcp is a standalone MCP server with stdio and Streamable HTTP transports for general-purpose Rust development grounded in Cargo and rustc. Discover a project offline, collect focused source context and compiler diagnostics, select individual tests, and run binaries/examples. Exact-version dependency docs, Rust Analyzer navigation and write-free change/refactor packages support deeper work.

Everyday workflow

The same workflow works with a library, CLI, service or multi-package Cargo workspace. No framework-specific project structure or particular MCP client is required.

Need	Tool call
Map packages, declared targets, features and dependencies without compiling	`workspace(action="inspect")`
Locate code and read bounded, numbered source	`workspace(action="search", query="parse_record")`, then `workspace(action="read", path="src/lib.rs", line=1, lineCount=80)`
Get fresh compiler diagnostics	`check(target="check", options={"packages":["my_crate"]})`
Discover actual test names	`test(action="list", packages=["my_crate"])`
Run one library test by its full name	`test(action="run", packages=["my_crate"], cargoTarget={"kind":"lib"}, filter="tests::parses_record", exact=true)`
Compile tests without executing them	`test(action="compile", packages=["my_crate"])`
Execute a binary or example	`run(package="my_crate", target={"kind":"example","name":"demo"}, args=["input.json"], timeoutMs=30000)`
Resolve an unfamiliar dependency API	`docs` with its exact version; `api` for deeper resolution/probing

Pass an absolute dir for the active project when the client starts elsewhere. A function is exercised through a test or executable example. run is a typed Cargo runner; program arguments remain literal, including spaces and shell metacharacters. Tests and applications execute project code with its ordinary side effects. Empty selections return NO_TESTS, not a passing test verdict.

Use agz-rust-mcp --toolset core for a compact catalog of six everyday tools: workspace, check, test, run, docs, and crate_lookup. The default --toolset full preserves every existing tool plus the new additions. Individual --tools-<name> false switches can disable tools further. See the full reference for limits and result states.

Install

bash

# installer script (Linux x86_64): download install.sh and SHA256SUMS from the# latest release, verify the script, then run itbash install.sh
# crates.io (requires Rust 1.91.0 or newer)cargo install agz-rust-mcp --lockedagz-rust-mcp --version

# installer script (Linux x86_64): download install.sh and SHA256SUMS from the# latest release, verify the script, then run itbash install.sh
# crates.io (requires Rust 1.91.0 or newer)cargo install agz-rust-mcp --lockedagz-rust-mcp --version

Prebuilt .tar.gz archives with .sha256 files are available for Linux x86_64, macOS arm64, and Windows x86_64. Releases up to 0.2.0 use the legacy agz-rust-coder-* asset names; from 0.3.0 onward the names are agz-rust-mcp-*.

MCP Client Setup

Use the installed executable with any client supporting local stdio MCP. Supply these fields in the client's own server configuration format:

json

{  "command": "agz-rust-mcp",  "args": ["--allow-root", "/absolute/path/to/project"],  "env": {"AGZ_RUST_MCP_SERVER__TOOLSET": "core"}}

{  "command": "agz-rust-mcp",  "args": ["--allow-root", "/absolute/path/to/project"],  "env": {"AGZ_RUST_MCP_SERVER__TOOLSET": "core"}}

For a client that uses HTTP, start the same binary as a local Streamable HTTP server and configure http://127.0.0.1:8787/mcp as its MCP URL:

bash

agz-rust-mcp --transport http --http-bind 127.0.0.1:8787 \  --allow-root /absolute/path/to/project

agz-rust-mcp --transport http --http-bind 127.0.0.1:8787 \  --allow-root /absolute/path/to/project

The HTTP listener is loopback-only. It supports the session lifecycle used by 2025-11-25 clients and the stateless 2026-07-28 protocol. Client-side display prefixes, configuration file locations, and automatic prompt selection belong to the client; the server depends on none of them. The canonical working directory is the default authorized root; client-provided roots can only narrow configured access. See connection details.

Built-in skills

Four offline skills ship inside the executable: agz-rust-workflow, agz-rust-repair, agz-rust-refactor, and agz-rust-performance. They are available immediately through all three standard MCP interfaces:

Tools: workspace(action="skills") lists the catalog; workspace(action="skills", skill="agz-rust-workflow") reads a skill.
Prompts: prompts/list and prompts/get expose workflow, repair, refactor, and performance.
Resources: resources/read exposes agz-rust-mcp://skills/<skill-name>.

A client that only exposes tools can use the complete skill content. Version and SHA-256 metadata identify the exact bundled instructions. No skill installation or separate MCP is required. Optional agz-rust-mcp skills export --dir <new-directory> creates files for clients that also support filesystem skills; existing files are never overwritten. See built-in skills.

Tools

These are the exact server tool names. Use the names returned by tools/list; a client may display its own namespace or prefix.

MCP tool	Default	Purpose
`workspace`	`enabled`	Read built-in skills, inspect manifests/lockfiles, search source and read excerpts offline.
`test`	`enabled`	Discover, compile or run selected tests with exact names, ignored-test controls and bounded execution.
`run`	`enabled`	Run an exact Cargo binary/example with literal arguments, a deadline and bounded output.
`check`	`enabled`	Run bounded Cargo check, Clippy, tests, docs, or the full gate.
`profile`	`enabled`	Analyze observed Cargo rebuild behavior and compare bounded build evidence without claiming unmeasured speedups.
`audit`	`enabled`	Scan Rust source for bounded static findings.
`crate_lookup`	`enabled`	Verify a crate and optional exact version on crates.io.
`docs`	`enabled`	Resolve exact-version docs from cache, local sources, or docs.rs.
`context`	`enabled`	Prepare, expand, or delta a revision-bound semantic context capsule with per-item reasons.
`api`	`enabled`	Resolve an API signature from bounded analyzer evidence or type-check a candidate snippet in an isolated copy of the workspace configuration.
`explain`	`enabled`	Explain macro expansion provenance, trait obligations, or cfg enablement.
`verify`	`enabled`	Plan or run a bounded feature, target, toolchain, and stage matrix.
`symbol`	`enabled`	Read Rust Analyzer hover data for one symbol.
`references`	`enabled`	Find bounded references.
`definition`	`enabled`	Find the selected definition.
`symbols`	`enabled`	List symbols in one Rust file.
`implementations`	`enabled`	Find implementations.
`hierarchy`	`enabled`	Trace a bounded call hierarchy.
`rename`	`enabled`	Produce a verified rename edit package without applying it.
`refactor`	`enabled`	Produce a verified refactor edit package without applying it.
`change`	`enabled`	Create, stage, migrate, and validate a revision-bound changeset in server-owned scratch without writing the workspace.
`repair`	`enabled`	Analyze, try, compare, and minimize compiler-driven repair candidates for a failing change revision without writing the workspace.
`work`	`enabled`	Drive a typed intent through change/validate with explicit gates and budgets, returning honest gate evidence or a bounded single-use handoff.

Every tool returns deterministic structured data plus an equivalent bounded text fallback. External data stays under untrustedData. Expected domain outcomes such as compiler failure, missing crates, or unavailable docs are typed results; invalid input, authorization failure, resource exhaustion, and unavailable semantic infrastructure are protocol errors.

Configuration

Precedence is CLI, then AGZ_RUST_MCP_* environment variables, then the explicit --config TOML file, then defaults. Environment keys use __ between sections, for example AGZ_RUST_MCP_GATE__HARD_TIMEOUT_MS=600000.

Key	Default	Meaning
`server.transport`	`stdio`	MCP transport: `stdio` or `http`.
`server.http_bind`	`127.0.0.1:8787`	Loopback address for the HTTP `/mcp` endpoint.
`server.allow_roots`	canonical CWD	Workspace read/command boundary.
`server.allow_dependency_roots`	empty	Explicit external path-dependency roots.
`gate.hard_timeout_ms`	`600000`	Cargo operation deadline.
`gate.scope`	`shadow`	Validation target: `workspace`, `shadow`, or `affected`.
`gate.cache`	`auto`	Cache policy: `auto`, `project`, or `isolated`.
`rust_analyzer.workspace_code`	`deny`	Reject RA startup unless workspace code is disabled.
`docs.fallback`	`auto`	Documentation source policy.
`profile.max_report_bytes`	`4194304`	Bounded read/store cap for one Cargo timing artifact.
`profile.max_runs`	`4`	Fresh Cargo runs available to one `profile` call.
`profile.compare_samples`	`3`	Required samples per side before any speed claim.
`limits.tool_output_bytes`	`49152`	Maximum serialized tool result size.
`change.max_bytes`	`268435456`	Maximum captured candidate bytes per changeset.
`repair.max_candidates`	`4`	Candidates one `repair` action may try.
`repair.max_compiles`	`4`	Cargo validations one `repair` action may run.
`repair.wall_time_ms`	`120000`	Wall-clock budget for one `repair` action.
`repair.minimize_max_candidates`	`32`	Compile-evaluated reduction attempts one `repair(action=minimize)` may try.
`repair.minimize_max_compiles`	`16`	Cargo runs one `repair(action=minimize)` may execute, including reproduction and export verification.
`work.max_candidates`	`4`	Host candidate revisions one work item may stage.
`work.max_compiles`	`12`	Gate validations one work item may run.
`work.wall_time_ms`	`600000`	Wall-time budget for one work item.
`telemetry.enabled`	`true`	Bounded local activity records without prompts or source.

profile evidence is bounded: the latest 64 records stay in memory, and persisted timing artifacts under the server-owned profile-evidence directory are pruned after 24 hours or beyond 64 files. The profile result reports this retention policy, so expired evidence is visible instead of silently reused.

Run agz-rust-mcp --help for every CLI field. The complete behavior and default table is in docs/tools.md.

Security

The server does not modify workspace source, but it is not an operating-system sandbox. Cargo build scripts, tests, procedural macros, local rustdoc, and opted-in Rust Analyzer workspace code execute with the server user's authority. Use a container or OS sandbox when that boundary is required. Workspace, dependency, cache, lease, journal, docs, and telemetry paths are canonicalized, bounded, and fail closed, and stdout is reserved for MCP framing. Report vulnerabilities privately as described in SECURITY.md.
