MCPtrace
Provides an MCP (Model Context Protocol) server that generates and executes bpftrace kernel tracing programs from AI assistant requests, including discovery/listing of available probes and asynchronous execution with later polling for results.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Security model relies on sudo access for bpftrace. README suggests storing a sudo password in a .env file and warns that there is no script validation (trust the AI client to generate safe scripts). No documented network transport security (TLS) or MCP-level authentication/authorization or scope granularity is provided in the README content. Also noted: resource limits (60s max execution, 10k lines buffer) but overall sandboxing/validation is not described.
⚡ Reliability
Best When
You have a Linux host with bpftrace available, are comfortable with an on-prem/local MCP server model, and want AI help generating kernel tracing scripts while managing sudo access securely.
Avoid When
You cannot enforce strong operational controls around sudo/password handling, or you require comprehensive, production-grade auth, rate limiting, and idempotency semantics.
Use Cases
- • AI-assisted Linux kernel debugging via natural language
- • Discovering kernel tracepoints/probes to monitor specific events
- • Tracing system calls, disk/network activity, and performance bottlenecks
- • Asynchronous capture of intermittent production issues with later retrieval of trace output
Not For
- • Use in environments where granting/handling sudo credentials is unacceptable
- • Real-time streaming requirements (only polling is described)
- • Workloads that require strict script validation/sandboxing before kernel tracing
- • Teams needing guaranteed API contracts, versioned stability, or enterprise-grade SLAs
Interface
Authentication
README describes sudo requirement and either a .env containing BPFTRACE_PASSWD or passwordless sudo for bpftrace. No explicit MCP auth scheme (e.g., API keys, OAuth) is documented; README mentions 'proper authentication' in the concept but also notes future enhancements.
Pricing
Open-source (MIT per repo metadata). No hosted pricing described; costs are operational (compute/host resources, tracing overhead).
Agent Metadata
Known Gotchas
- ⚠ No real-time streaming; agents must poll via get_result using execution_id.
- ⚠ No script validation/sandboxing is described; an agent may generate unsafe/overly expensive bpftrace programs if not constrained by the client.
- ⚠ Server requires sudo/bpftrace; failures will occur if sudo is not configured or credentials are missing/incorrect.
- ⚠ Asynchronous execution buffers/results may require careful cleanup/timeout handling; behavior is described only at a high level.
- ⚠ Retry behavior/idempotency semantics are not clearly documented; repeated exec_program calls may generate multiple independent trace executions.
