# MCP Mastery Heuristics
When working with Model Context Protocol (MCP) servers:
1. **Schema Discovery**: Call `tools/list` on startup. Adhere strictly to the argument types in `inputSchema`.
2. **STDIO Rules**: On stdio transports, never print raw console logs to STDOUT. STDOUT is reserved exclusively for JSON-RPC 2.0 frames. Use STDERR for all logs.
3. **Windows Paths**: In config files on Windows, escape backslashes (`"C:\\\\Path"`) or use forward slashes (`"C:/Path"`).
4. **Error Recovery**:
- `-32602 (Invalid Params)`: Inspect `inputSchema` requirements and re-dispatch with corrected types.
- `-32603 (Internal Error)`: Check STDERR logs for unhandled exceptions or STDOUT corruption.
- `ENOENT`: Replace command with absolute binary path (e.g. `C:/Program Files/nodejs/npx.cmd`).
Autonomous Tool Chaining Recipes
Real-world patterns where agents orchestrate multiple MCP servers in sequential loops.
Production Sentry Incident -> GitHub Issue Triage
sentry.list_issues
Query unresolved Sentry errors with event_count > 100 in the last 24 hours.
sentry.get_event_stacktrace
Extract root-cause file path and line number from the crash event stack trace.
github.search_code
Find matching source code lines in the repository to locate faulty commit.
github.create_issue
Create GitHub issue containing error frequency, stack trace snippet, and suggested fix.
slack.post_message
Notify #oncall-engineering channel with link to newly created GitHub issue.
PostgreSQL Data Analysis -> Markdown Report Export
postgres.describe_table
Inspect schema of orders, users, and subscriptions tables.
postgres.query
Execute aggregate monthly recurring revenue (MRR) calculation query.
filesystem.write_file
Write formatted Markdown summary table with KPIs to ./reports/monthly-mrr.md.
Brave Search -> Fetch Deep Reading -> Knowledge Graph
brave_search.brave_web_search
Search for latest technical RFCs on AI agent standards.
fetch.fetch_markdown
Fetch full article content from top 3 search results as clean Markdown.
memory.create_entities
Persist extracted key entities and relationships into persistent memory graph.
Direct Machine-Readable Endpoints
Connect external agent runtimes directly to MCP Codex data feeds.
Compact, structured summary of MCP Codex designed for LLM context ingestion.
Comprehensive manual containing all protocol specs, schemas, and 50+ verified server configs.
Standard agent skill markdown with system instructions.
Full machine-readable registry of verified MCP servers, arguments, env schemas, and tools.
Machine-readable database of error codes, root causes, symptoms, and JSON config fix patches.
