backlog-mcp-server-rust
Backlog MCP server that exposes Backlog (project management) functionality as an MCP server with tools for reading and, optionally, writing to issues, PRs/comments, wiki pages, documents, shared files, and listing users/status/custom fields.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Uses BACKLOG_API_KEY via environment variables as the primary credential mechanism. README does not describe MCP-level logging/redaction, nor TLS/HTTP details for outbound calls (assumed HTTPS to Backlog base URL). Authorization appears coarse (single API key) with optional project allowlisting via BACKLOG_PROJECTS; no fine-grained per-tool scopes are described. Dependency hygiene and vulnerability status are not evidenced in the provided content.
⚡ Reliability
Best When
You want an MCP-compatible agent workflow for Backlog that can be constrained to specific projects and optionally limited to read-only by building without writable features.
Avoid When
You cannot securely supply/store BACKLOG_API_KEY or you need clear documented guarantees about rate limiting, retries, and error semantics from the MCP server.
Use Cases
- • Automate issue research and summarization from a Backlog space
- • Create/update issues and comments with AI-assisted workflows
- • Manage wiki content and attachments via MCP-enabled agents
- • Browse PRs and add PR comments using an AI agent
- • Download and analyze attachments/documents from Backlog
Not For
- • Public multi-tenant deployment without careful credential handling
- • Use cases requiring fine-grained role-based authorization beyond the Backlog API key permissions
- • Environments that require a documented SLA/status or detailed operational guarantees
Interface
Authentication
Authentication is handled by Backlog API key supplied to the MCP server via environment variable. No OAuth flows or documented fine-grained scopes at the MCP layer are described.
Pricing
Pricing is not described for the MCP server itself; Backlog API usage is dependent on your Backlog plan.
Agent Metadata
Known Gotchas
- ⚠ Write operations are controlled via Cargo feature flags (issue_writable, git_writable, wiki_writable, document_writable); deploying a server without the intended features may cause missing-tool behavior.
- ⚠ Tool name prefix can be changed via BACKLOG_PREFIX; agents relying on exact tool names should confirm effective prefix configuration.
- ⚠ Tool set includes both read and write tools; agents should be configured/allowed with least-privilege tool lists to avoid unintended changes.
