From 6a8dfa8b66ab765c0ccd2eaed4f29347c2a9dfb0 Mon Sep 17 00:00:00 2001 From: Ryan Parmeter Date: Mon, 10 Nov 2025 16:43:11 -0700 Subject: [PATCH] feat: Add binary path resolution and Docker support (v0.1.0) This release adds intelligent binary discovery and Docker support to Tendril, making it more flexible and cross-platform compatible. ## Features ### Binary Path Resolution - Intelligent binary discovery with smart fallbacks - Explicit user configuration via gitea_mcp_binary_path setting - Standard system paths (/usr/local/bin, /usr/bin) - User home directories (~/.local/bin, ~/.cargo/bin, ~/bin) - Platform-specific paths (/opt/homebrew/bin on macOS M-series) - System PATH environment variable search - Robust WASM sandbox handling for filesystem checks - Comprehensive error messages with troubleshooting guidance - Removed hardcoded /usr/local/bin/gitea-mcp path ### Docker Support - New use_docker configuration option for containerized deployment - New docker_image configuration for custom images (default: gitea/gitea-mcp-server:latest) - Automatic docker binary detection at /usr/bin/docker or other standard locations - Proper gitea-mcp command-line flag formatting (-token, -t stdio, -host, -insecure) - STDIO communication through Docker containers ### Cross-Platform Support - Linux: Standard system and user paths - macOS Intel: Same as Linux - macOS M-series (ARM64): Optimized for /opt/homebrew/bin - Windows: Program Files paths (code ready, untested) - Proper PATH separator handling (: on Unix, ; on Windows) ## Bug Fixes - Fixed WASM sandbox filesystem access limitations - Corrected Docker image name to gitea/gitea-mcp-server:latest - Fixed Docker command flag formatting for gitea-mcp arguments - Improved error handling with helpful resolution steps ## Documentation - Updated README.md with Docker mode examples and configuration reference - Expanded DEVELOPMENT.md with architecture and testing roadmap - Updated PROJECT_STATUS.md with v0.1.0 feature status - Updated configuration with all new options and detailed comments - Added comprehensive inline code comments ## Testing - Binary mode auto-detection: Tested and working - Binary mode custom path: Tested and working - Docker mode with default image: Tested and working - Self-hosted Gitea instances: Tested and working - Self-signed certificate support: Tested and working ## Files Changed - src/mcp_server_gitea.rs: Core extension (~350 lines) - configuration/default_settings.jsonc: New settings - configuration/installation_instructions.md: Updated guide - README.md: Expanded documentation - DEVELOPMENT.md: Complete developer guide - PROJECT_STATUS.md: Updated status - .gitignore: Added comprehensive ignore file ## Breaking Changes None - fully backward compatible. ## Next Steps (v0.2.0) - Cross-platform testing - Interactive configuration wizard - Performance optimizations - Marketplace publication --- .gitignore | 52 ++ Cargo.toml | 15 + DEVELOPMENT.md | 550 +++++++++++++++++++++ PROJECT_STATUS.md | 490 ++++++++++++++++++ QUICKSTART.md | 130 +++++ README.md | 522 ++++++++++++++++++- SSE_MODE_ANALYSIS.md | 197 ++++++++ TESTING_FINDINGS.md | 211 ++++++++ ZedExtensions.md | 138 ++++++ configuration/default_settings.jsonc | 61 +++ configuration/installation_instructions.md | 28 ++ extension.toml | 10 + src/mcp_server_gitea.rs | 359 ++++++++++++++ 13 files changed, 2761 insertions(+), 2 deletions(-) create mode 100644 .gitignore create mode 100644 Cargo.toml create mode 100644 DEVELOPMENT.md create mode 100644 PROJECT_STATUS.md create mode 100644 QUICKSTART.md create mode 100644 SSE_MODE_ANALYSIS.md create mode 100644 TESTING_FINDINGS.md create mode 100644 ZedExtensions.md create mode 100644 configuration/default_settings.jsonc create mode 100644 configuration/installation_instructions.md create mode 100644 extension.toml create mode 100644 src/mcp_server_gitea.rs diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..9674673 --- /dev/null +++ b/.gitignore @@ -0,0 +1,52 @@ +# Rust +/target/ +Cargo.lock +**/*.rs.bk +*.pdb + +# Build artifacts +*.o +*.a +*.so +*.dylib +*.dll +*.lib +*.def + +# IDE +.idea/ +.vscode/ +*.swp +*.swo +*~ +.DS_Store +*.sublime-project +*.sublime-workspace + +# Zed +.zed/ +*.wasm +.zedstate + +# Development +.env +.env.local +*.log + +# OS +.DS_Store +.DS_Store?

An example directory structure of an extension that provides all capabilities is as follows: +``` +my-extension/ + extension.toml + Cargo.toml + src/ + lib.rs + languages/ + my-language/ + config.toml + highlights.scm + themes/ + my-theme.json +``` + +## WebAssembly +Procedural parts of extensions are written in Rust and compiled to WebAssembly. To develop an extension that includes custom code, include a Cargo.toml like this: + +``` +[package] +name = "my-extension" +version = "0.0.1" +edition = "2021" + +[lib] +crate-type = ["cdylib"] + +[dependencies] +zed_extension_api = "0.1.0" +``` + +Use the latest version of the zed_extension_api available on crates.io. Make sure it's still compatible with Zed versions you want to support. + +In the src/lib.rs file in your Rust crate you will need to define a struct for your extension and implement the Extension trait, as well as use the register_extension! macro to register your extension: + +``` +use zed_extension_api as zed; + +struct MyExtension { + // ... state +} + +impl zed::Extension for MyExtension { + // ... +} + +zed::register_extension!(MyExtension); +``` + +stdout/stderr is forwarded directly to the Zed process. In order to see println!/dbg! output from your extension, you can start Zed in your terminal with a --foreground flag. + +# MCP Server Extensions +Model Context Protocol servers can be exposed as extensions for use in the Agent Panel. + +## Defining MCP Extensions +A given extension may provide one or more MCP servers. Each MCP server must be registered in the extension.toml: + +``` +[context_servers.my-context-server] +``` + +Then, in the Rust code for your extension, implement the context_server_command method on your extension: + +``` +impl zed::Extension for MyExtension { + fn context_server_command( + &mut self, + context_server_id: &ContextServerId, + project: &zed::Project, + ) -> Result { + Ok(zed::Command { + command: get_path_to_context_server_executable()?, + args: get_args_for_context_server()?, + env: get_env_for_context_server()?, + }) + } +} +``` + +This method should return the command to start up an MCP server, along with any arguments or environment variables necessary for it to function. + +If you need to download the MCP server from an external source—like GitHub Releases or npm—you can also do that in this function. + +## Available Extensions +An example Zed Extension for the Gitlab MCP is in `config/mcp/gitlab-mcp-zed/`. + +For the BCOS project, we will develop a Gitea MCP Extension based on this example. This extension will integrate with our Gitea instance to provide seamless access to our repository from within the Zed IDE. + +## BCOS-Specific Integration +For the BCOS project, MCP server extensions will be stored in `/config/mcp` according to our monorepo structure.
