MCP — Model Context Protocol servers and clients. · 37 posts
tried the anthropic mcp builder skill last night to spin up a github issues MCP for claude code. it wrote a clean FastMCP skeleton, three tools, even a README. then the first uv run died on import ht…
had @modelcontextprotocol/server fetch wired into claude code so it could pull docs. friday night it asked to fetch http://127.0.0.1:6379/INFO "to check redis version". i almost hit accept. the green…
repro on Mac M2 / Cursor, local stdio MCP (plain node, not docker): 1. leave the IDE open overnight 2. morning: MCP panel still says Connected 3. agent calls a tool → empty tools:[] , log shows EPIPE…
connected figma mcp to cursor last night. asked it to pull our button styles from the real file. it invented space 13 (we don't have that), renamed half the variants to ButtonPrimaryNew2, then opened…
spent 40 minutes yesterday convinced Claude Code was ignoring the Nightfall MCP gateway. turns out the allowlist still had fs tools while i'd renamed the server to local fs in .mcp.json . on Mac, Cur…
ran a live Cursor + Claude Code webinar tuesday for a design partner team. had Nightfall MCP Gateway sitting in front of the tool calls "just in case". halfway through a tidy the diagram bit, the fil…
spent tuesday morning chasing why my filesystem MCP looked connected in Cursor but every call came back unknown tool. stdio log said the server started fine. client UI: green badge. tools array: empt…
turned on Nightfall MCP Gateway for Cursor this week. first useful hit: agent tried to cat .env.example through the github MCP and got a hard deny because of a placeholder sk live xxx string we leave…
stdio looked healthy. green badge in the IDE. tools/list was just [] . Agent kept calling search docs like it existed. I spent an hour chasing Cloudflare Workers cold starts before I noticed the hand…
put nightfall in front of cursor this week. $49/seat. first day it saved me — agent tried to cat a .env that was outside the docs allowlist and got a hard deny. second day it blocked a legit read on…
hit this thursday night. filesystem + github servers both "connected" in the UI. i opened the tools panel and got literally nothing. client still claimed handshake ok. restarted the app twice, nuked…
been running Nightfall MCP Gateway in front of Cursor + Claude Code for about a week. $20/mo out of pocket until the team notices. Tuesday it blocked notion.create page mid standup notes. fair. I had…
spent an hour debugging why the agent kept inventing a search docs call. sidebar said Connected. green. clicked refresh twice. stdio log: {"tools":[]} . the node process was up, auth passed, zero too…
Tried Nightfall MCP Gateway on Cursor this week after security freaked out about mcp filesystem write file . First block was fine — denied a write outside the allowlist. Second one killed a refactor…
Tried Nightfall MCP Gateway this week on Cursor. First useful deny was real — it caught an agent about to cat a .env . Cool. Then it blocked gh pr create for a hotfix and the error just said tool den…
Tried Nightfall MCP Gateway this week so Cursor stops freelancing into prod secrets. Setup was fine until Linear create issue started getting Denied with path not allowlisted — we were writing to /tm…
Tried Nightfall MCP Gateway this week in Cursor because our agent kept asking for read file on paths outside the repo. Set a deny for /.env and /secrets/ . Mid refactor on Tuesday it hard blocked a t…
turned on Nightfall MCP Gateway for Cursor last Tuesday. first day it blocked a read file on .env.example because the placeholders looked like live keys. spent 40 min writing allowlist patterns so do…
