Use when the BlockRun MCP server (@blockrun/mcp) is installed but misbehaving — 'Failed to connect', spawn npx ENOENT, blockrun missing from claude mcp list, HTTP 402 / Insufficient balance, fetch failed, video or music timeouts, a 501 'not served' error or 'API error after payment' while the balance never moved, spend-confirmation dialogs not appearing, or a Polymarket buy/redeem failing after funding. Symptom → cause → fix, plus what never to do.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Debugging BlockRun MCP Find the row, run the fix, stop. Most "broken" reports are one of the first three rows. ## Rules before touching anything 1. **A 402 / "Insufficient balance" is a funding state, not a bug.** Call `blockrun_wallet` first. Never retry the failing tool in a loop — it will 402 identically every time and the failed attempts cost nothing, but they burn turns. 2. **Never delete or regenerate `~/.blockrun/.session`.** It is the only copy of the key that holds the user's USDC and their Polymarket deposit wallet. There is no recovery. 3. **Never advise withdrawing from Polymarket to "start over".** Every post-funding trade failure seen so far was a missing approval; a withdraw does not fix it and costs a round trip. 4. Reproduce with the **free** call `blockrun_wallet` before anything paid. ## Run these first (read-only, 10 seconds) ```bash node -v && which npx # runtime present, ≥ 20.19? claude mcp get blockrun # registered command, env, AND scope (-s user / project / local) npx -y @blockrun/mcp@latest --version # does the package itself run? (prints e.g. 0.43.0) ``` …

How to install
mdr add blockrunai/blockrun-mcp/blockrun-debug@sha256:9713742c2a9fbd13The line at the top of this page pins the label git:20260915.c39cc81, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
