WallChartBook MCP server
Which MCP servers are WallChartBook's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

- Registry namecom.wallchartbook/siteverified in the MCP registry
The registry name sits under wallchartbook.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-25 the server answered initialize and tools/list without a sign-in. First answer in 1086 ms.
- Whether its tools do the product's job has not been judged yet.
Once connected
- Parameters are untyped or undescribed in 5 of 7 tools: check arguments before calling.
Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

What an agent can do with it
- not sure · work out pro rata annual leave for starters and leavers

- cannot · record each leave request against the employee's balance
Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?
Worth a look
None of the five warning signs in these definitions.
A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →
dataset_columnsThe columns, which of them are numeric, the row count and the provenance banner of the WallChartBook dataset. Call this first to learn the schema.
dataset_searchRows of the WallChartBook dataset whose cells contain the query (case-insensitive), up to 50.
dataset_rowThe rows of the WallChartBook dataset where a column equals a value exactly (case-insensitive).
dataset_compareThe rows of the WallChartBook dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
dataset_statscount, min, max, mean, median and sum of a numeric column of the WallChartBook dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
dataset_topThe highest (or lowest) rows of the WallChartBook dataset by a numeric column — "which is the most/least X".
dataset_provenanceThe source, the date it was computed, the licence and the citation for the WallChartBook dataset. Read this to attribute a figure correctly.
How to connect
Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:
{
"mcpServers": {
"site": {
"type": "http",
"url": "https://wallchartbook.com/mcp"
}
}
}Add it
Claude Code, in a terminal
claude mcp add --transport http wallchartbook https://wallchartbook.com/mcpclaude.ai, ChatGPT and other clients: add https://wallchartbook.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
