Build, configure, and debug the Meridian MCP server. An agent skill from Meridiona/meridian.

What it does

Meridian MCP is an agent skill from Meridiona/meridian. Build, configure, and debug the Meridian MCP server. Exposes app session data to AI tools via the Model Context Protocol.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol, WebAssembly, SQL and Node.js. The repository describes itself as: Stop letting your work go unnoticed. Meridian keeps an automatic work journal of what you worked on and what you finished, summarised daily, and automatically drafts your project…

When your agent uses it

  • Tasks that involve MCP servers

Example prompts

  • “/meridian-mcp”

Requirements

  • Node.js
  • Pre-approved tools (allowed-tools): Bash, Read, Edit, Grep, Write

What it can do on your machine

Read from SKILL.md and the folder at commit 06af902. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read
    • Edit
    • Grep
    • Write

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • node
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm and npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Meridian MCP loads about 967 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 305 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~967

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read, Edit, Grep, Write

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 305 words (~967 tokens).

“A TypeScript MCP server (packages/meridian-mcp/) that exposes Meridian's structured session database to any MCP-compatible AI tool (Claude Code, Claude Desktop, Cursor, etc.).”
