Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

describe

describe_schema

One type's schema as the instance vendors it: file location, frontmatter fields, sections and their columns, purpose and writing rules.

entities

list_entities

The id, canonical name and tagline of every entity of one type.

entity

get_entity

One entity by type and canonical name: its frontmatter, sections and tables, with every reference it makes and every reference made to it. A name resolves within its type.

evidence

find_evidence

Everything the model says about one skill: each profile's claimed level with its Evidence verbatim, each experience that lists the skill, and any other page that references it.

fetch

fetch

One entity by the id search returned, with its page as written. A bare name is accepted only when exactly one type holds it.

search

Entities whose name, tagline, fields, sections or table cells contain the query, case-insensitive, listed by type then name with the fields that matched. Use fetch with a result's id.

types

list_types

Every type the instance's schemas declare, with its tagline, its owner type and how many entities it holds.

Robert Blust — questions

Answers built from our own checks of this server.

What can Robert Blust do?

It exposes 7 tools, read directly from the server on our last check. Among them: describe_schema, fetch, find_evidence, get_entity, list_entities, list_types and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Robert Blust working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 67 of 67 checks got a reply (100.0%), average response time 168 ms. The bar chart above shows every period we have measured.

How do I connect Robert Blust?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Robert Blust need an API key?

No. Robert Blust completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Robert Blust?

It answers our handshake in 168 ms on average, which is faster than 73% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
